__module__ is the string name of the module the function was defined
in, just like __module__ of classes. In some cases, particularly for
C functions, the __module__ may be None.
Change PyCFunction_New() from a function to a macro, but keep an
unused copy of the function around so that we don't change the binary
API.
Change pickle's save_global() to use whichmodule() if __module__ is
None, but add the __module__ logic to whichmodule() since it might be
used outside of pickle.

(Same problem as last checkin for SF bug 610610)
Need to clear the error and proceed.
Backport candidate
|
| |
|
|
|
|
|
|

The switch in Exception__str__ didn't clear the error if
PySequence_Size() raised an exception. Added a case -1 which clears
the error and falls through to the default case.
Definite backport candidate (this dates all the way to Python 2.0).

calling PyString_Check(NULL).)

new slot tp_iter in type object, plus new flag Py_TPFLAGS_HAVE_ITER
new C API PyObject_GetIter(), calls tp_iter
new builtin iter(), with two forms: iter(obj), and iter(function, sentinel)
new internal object types iterobject and calliterobject
new exception StopIteration
new opcodes for "for" loops, GET_ITER and FOR_ITER (also supported by dis.py)
new magic number for .pyc files
new special method for instances: __iter__() returns an iterator
iteration over dictionaries: "for x in dict" iterates over the keys
iteration over files: "for x in file" iterates over lines
TODO:
documentation
test suite
decide whether to use a different way to spell iter(function, sentinal)
decide whether "for key in dict" is a good idea
use iterators in map/filter/reduce, min/max, and elsewhere (in/not in?)
speed tuning (make next() a slot tp_next???)

make_class(): Added a "goto finally" so that if populate_methods()
fails, the return status will be -1 (failure) instead of 0 (success).
fini_exceptions(): When decref'ing the static pointers to the
exception classes, clear out their dictionaries too. This breaks a
cycle from class->dict->method->class and allows the classes with
unbound methods to be reclaimed. This plugs a large memory leak in a
common Py_Initialize()/dosomething/Py_Finalize() loop.

First, the allocated buffer was never freed after using it to create
the PyString object. Second, it was possible that have_filename would
be false (meaning that filename was not a PyString object), but that
the code would still try to PyString_GET_SIZE() it.

file name included in the exception message short.

than depending on the site that raises the exception. If the
filename and lineno attributes are set on the exception object,
use them to augment the message displayed.

(Jitterbug PR#278).

comments, docstrings or error messages. I fixed two minor things in
test_winreg.py ("didn't" -> "Didn't" and "Didnt" -> "Didn't").
There is a minor style issue involved: Guido seems to have preferred English
grammar (behaviour, honour) in a couple places. This patch changes that to
American, which is the more prominent style in the source. I prefer English
myself, so if English is preferred, I'd be happy to supply a patch myself ;)
